A manufacturing method of a semiconductor device using a semiconductor manufacturing unit comprising a reaction chamber, a substrate mounting stage, and a high frequency power supply coupled to the substrate mounting stage, a blocking capacitor interposed between the substrate mounting stage and the high-frequency power supply to continuously perform a plurality of dry etching processing with respect to the same substrate in the same reaction chamber, the method includes: disposing a substrate on a substrate mounting stage, and applying high-frequency powers to the substrate mounting stage while introducing a fluorocarbon-based first gas to perform a first dry etching processing with respect to the substrate, the substrate including an organic material film and a silicon compound film sequentially deposited on a surface thereof and a resist film patterned on the silicon compound film, the first dry etching processing including processing the silicon compound film with the resist film being used as a mask; and stopping application of one of the high-frequency powers, thereby reducing a bias voltage generated to the substrate while introducing a second gas after the first dry etching processing to remove a fluorocarbon-based deposition in the reaction chamber and perform a second dry etching processing with respect to the substrate.
Abstract:
A first silicon containing film, an organic material film, a second silicon containing film are formed. The second silicon containing film is patterned to have a narrow width pattern and a wide width pattern. The organic material film is patterned to have a narrow width pattern and a wide width pattern. A side wall is formed on a side surface of the second silicon containing film and the organic material film by coating with a third silicon containing film. The narrow width pattern of the second silicon containing film is removed by using a mask that covers the second silicon containing film patterned to have a wide width pattern and the side wall. Finally, the organic material film is removed.
